VACUUM Application led Hay 18,

The main object of this invention is to Referring briefly to the drawing, Figurel 15 1 is a longitudinal sectional elevational view of 4the dirt hopper, showing the vacuum cleaner mounted in place thereon.

Figure 2 is a top-plan view of Figure 1.

Figure 3 is a side elevational view of Figure 1.

Figure 4 is a fragmentary sectional elevational view, showing a mp-dilied type of baffle plate and its means for detachably mounting the same in place.

Referring in detail to the drawing, the numeral indicates the upper side walls of ahopper. These side walls are joined by end walls 11 which form a rectangular con- `tainer closed at the top by a hinged cover 12. 30 \The lower edges of these Walls are inclined l toward each lother as indicated by the numeral 13, providing'a funnel, and at the restricted portion of these inclined walls, a 'wire mesh '14 is udet'achably seated.' A neck 15 extends from the inclined walls downwardly to the floor. One of the side walls 16 of this neck is shorter than the remaining portions and has mounted thereto a roof 17 of a dirt trap which consists of a loor plate 18 and an end wall 19 which encloses achamber 20. A'rectangular opening 21 eX- tends partly across the width of the roof 17 and beside one side of the Opening, a stop ridge 22 projects upwardly from the roof and serves asa member which limits and guides the mouth 23 of a vacuum cleaner 24 to come to rest over the opening 21. The chamber formed by the neck walls receives a plurality of inclined baille plates 25 which 50 rise towardvthe center of the chamber. One of the walls 10 facing the free end of the hinged cover 12 is provided with a semi-circular opening 26 thru which the mop end 27 is inserted into the compartment 28.

In Figure 4, a modified form is shown in which the baille plates are made detachable CLEA-NEB.

so that they may be removed when it is desired not to use the same. These balle plates are mounted in place by sliding the 'same first upwardly into the channel, 33 of a guide plate 32 of relatively longer dimensions than the plate 3l described below, to permit vertical sliding in the channel 33. A retainer plate 31 'of the same outline as member 32,

but of shorter dimensions, is mounted below the ballle plate 34. The latter has attached' thereto a tongue 35 whose end rests in the -channel 30. In inserting the bales, the tongue 35 is slid vertically upward into channel 33, then said tongue is brought flush against the Wall 15 or 16, and depressed so that the lowerend of thetongue rests in the channel 30.

The hopper is used for extracting dirt or the like from mops and similar other sweeping articles such as brooms. The handle29 of the mop 27 or other article which is to be cleaned is grasped and the active endof said article is inserted into the semi-circular opening. so that said end projects into the cham# ber 28. A vacuum cleaner, whose mouth 23' completely covers the rectan ular opening 21 byrbackin'g the vacuum c eaner against the ridge, is supported on one side of the device. The current of air in the vacuum cleaner is then generated and the air enters thru the mouth of the vacuum cleaner and causes a circulation of air from chamber 28 thruthe neck, passing,v the ballie plates 25 and thence entering the chamber 20 after which it passes directly into the dust bag attached to the vacuum cleaner. Articles such as screws or solid material, which is likely to adhere to the mopuntil it arrives in the cleaning hopper, when dislodged fall upon the wire mesh screen 14, and when this is not used, such articles fall upon the balile plates 25 or the modified type of bale plates It is to be noted that certainchan es in bform and construction may bemade wlthout departing from the spirit and scope of the invention.

1. A device of the class described comprising a hopper having an opening in one side adapted to receive the. head of a mop or the like, a hin ed door-normally closing said hopper, ba e p1ates,'a neck htegralfwith said hopper and beneath thesani'e, and means for detachably mounting said baillel platesfin inclinedlposition in the neck of said hopper,

2. A device of the class described compris-- 'adapted to receive the head of a. mop, or the like, a hinged door normally closing said hopper, baille plates, a neck integral with said hopper and beneath the same, tongues on said baffle plates, and means in said neck cooperating with said tongues for detachably mounting said tongues rigidly in said neck in inclined position.

3. A device of the class ldescribed comprising a hopper having an opening in one side adapted to receive the head of a mop or the like, a hinged door normally closing said hopper, balle plates, a neck integral with Leanne? said hopper and beneath the same, tongues on said baille plates, means in said neck cooperating with said tongues for detachably mounting said tongues rigidly in said neck in inclined position comprising guide plates forming an upper channel and a lower channel, the upper channel being deeper than the lower channel, said tongue being adapted to be slipped into the upper channel, slid up# wardly and then lowered into the lower channel to detachably secure each of said baille plates in place in the neck.

In testimony whereof I aflix my signature.
